Serial No. 245,908.

To all whom it may concern Be it known that I, FaANKLIN W. OnH'nLn, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented an Improvement in Machines for Making Ornamental Rope or Cord, of which the following is specification.

My invention relates to improvements in machines or apparatus for the manufacture of ornamental rope or cord, and it has for one of its objects to provide a construction in which the spool or equivalent carrier for the inner binding thread is supported in a new and novel manner with respect to other parts of the machine or apparatus.

Other objects and advantages of my invention will be hereinafterreferred to in the descriptive portion of this specification 1 or will become apparent therefrom.

One form of a convenient embodiment of my machine or apparatus is illustrated in the accompanying drawings but 1t wlll be understood that changes in the details of construction or arrangement of the parts may be made within the scope of the claims without departing from the said invention.

In the drawings 2 Figure 1 is a longitudinal sectional elevation of a machine or apparatus embodying my invention;

Fig. 2 is an end elevationlooking toward the right in Fig. 1;

Fig. 3 is a transverse section on the line 3-3 of Fig. 1; and

Fig. 1 is a longitudinal sectional elevation of a modified construction of machine, the rear end portion thereof being broken away.

Referring to the drawings 1 designates the base portion of a machine and 2, 3 and 4 designate supporting posts and the last of which are located at the.

ends while the plug or blocl; 17 is locatedintermediate the ends of the said revoluble Specification of Letters Patent.

Patented July 15, 1919:

This application filed J'u1y member in alinement with the upright supporting post 8. The said plugs or blocks are secured in position within the revoluble member 10 by means of screws 20, only one .of whicliis shown in connection with each of the said plugs or blocks. I

The revoluble member 10 is held against loi'i'gitudina1 movement in its hearings in the supporting posts 2, 3 and- 1 by means of a flange 21 upon the outer end of the block 18 which rests against the outer side of the supporting post a which flange cotiperates with the flange 22 uponthe gear 15 which is situated in contact with the opposing side of the said supporting post 4.

Holes 23 are provided in the plugs or blocks 17 and' 18 which holes are coaxial withthe axis of revolution of the revoluble member 10' and the said plugs or blocks 17 and 18.

An inner binding thread guide member 24: is supported in the said holes and is secured therein by meanS' of a sleeve 25 secured thereon and which is situated in contact with theinner side of the plug or block 18. The presence of the said sleeve prevents longi- ,tudinal movement of the said guide member to the right in Fig, 1. Movement of the said guide member 24 in the opposite direction is larevented by the hub of the gear wheel 26 which is secured to the said guide member upon the outside of and adjacent to the plug or block 18. The said guide member 24 also serves as a support for a deta chableforiner 28 secured upon the outer forward end thereof by means of a binding screw 30 which passesthrough a collar 32 and engages the forward end portion of the guide member 245. The inner binding thread 85 passes through a hole through the guide member'24 and through the former 28.

The former being secured to and supported upon the innerthread guide member 2% which in turn is supported uponthe revoluble plugsor blocks 17 and 18 it follows that the said former would rotate unless means should be provided for the prevention of such rotation.

It is necessary that the former should be made stationary and forthis purpose I have provided the gear mechanism illustrated in det'ailin Fig. 30f the drawings, in which, 40 designatesa gear secured to a member 41 which serves as a guide for the ornamental loop threads of the rope or cord and which while revolving with the revoluble member 10 is held against rotation 011 its own axis. The said member 11 is supported in openings 4-3 in the plugs or blocks 16, 17 and 18.

i5 designates an intermediate gear rotatably mounted upon a pivot 46 secured to the plug 18. The said gear 45 also revolves with the revoluble member 10 around the axis of the said revoluble member. The gear 45 is in engagement with both the gears 26 and a0. The revoluble member 10 revolves in the direction indicated by the arrow 47 in Fig. 3 and as a result of the fact that the gear %0 is held stationary upon the guide member 11, although being revolved around the gear 26, and as it is constantly changing its position with respect to the gear 45, being at times in horizontal alinement therewith, at other times in vertical alinement there with, and at other times occupying intermediate positions with respect thereto, it causes rotation of the gear 45 to the left about its pivot 16.

By reason of the fact that the gear 15 meshes with the gear 26 it tends to rotate the latter to the right (having reference to Fig. 3) in consequence of which the rotation of the gear 26 and the parts 2 1 and 28 connected therewith with the revoluble member 10 on which they are carried, is prevented and the said gear and the parts connected thereto are held stationary.

The ornamental thread guide 41 is held against rotation on its own axis by means of its connection with the upper end of a link 50 pivotally connected at 51 to a link 52 pivoted at 53 to the base of the machine. The ornamental binding threads 55 are supplied from a plurality of spools or equivalent carriers supported upon a rack at the rear of the machine, the said spools and the rack being, however, omitted from. the drawing.

60 designates an outer binding thread which is supported in operative relation to the former 28 by means of a roller 61 which in addition to supporting the said binding thread also operates to control and feed the ornamental threads which have been wound upon the former 28 therefrom. The inner and outer binding threads 35 and 60 are twisted together and are pulled and fed forwardly, that is toward the right having reference to Figs. 1 and 2, by means of a twisting device not illustrated.

Although the revoluble member 10 is shown as being hollow and being provided with plugs therein for the purpose stated, it will be understood that the construction of the said revoluble member may be varied and changed in various ways without in any way affecting my invention.

Referring to Fig. 1, designates a spool supported upon a rod or spindle 71 which is secured to and supported upon the plug or block 16 at the rear of the revoluble member 10. The said rod 71 is secured upon the said plug or block 16 by means of nuts 72 and 73 the former being secured the left hand side of Fig. 1 and being in contact with the outer side of the plug 16 while the latter is secured at the inner end of the said rod.

74: designates a washer situated between the spools 70 and the plug or block 16 and 7 5 designates a washer situated between the inner end of a friction spring 7 6 and the adjacent end of the spool 70. The friction spring 76 is located at the inner end of the rod 71 between the said washer and the nut 73. The tension of the said spring may be varied by varying the position of the nut 73.

The spool 70 containing the supply of inner binding thread 35 is located interiorly of and eoaxially with the revolu'ble member 10. The binding thread is led from the said spool through eyes 80 upon the inside of the said revoluble member 10. The inner binding thread is so wound upon the said spool that the revolution of the member 10 causes revolution of the said spool in the same direction and at the same speed as the said revoluble member in consequence of which the point at which the thread is taken from the spool is maintained in constant relation to the ornamental thread guide 41 and the threads guided thereby.

In addition to the revolution of the spool caused by the revolution of the member 10 it is given an additional speed of revolution due to the drawing forward of the binding thread 35 by the twister (not shown) as.

above stated.

The presence of the friction springs 76 prevents the spool from overrunning itself.

In order that the spool or carrier 70 may be removed for the purpose of placing a new spool upon the spindle 71 or for any other purpose, I have provided openings 81 in the revoluble member 10 only one of which is shown. If preferred, but one opening may be provided or if the size of the revoluble member admit, the number of the openings may be increased.

Referring to Fig. 4 of the drawings, I have shown a modified construction differing from Figs. 1 to 3 of the drawings only in the manner of mounting the spool which supports the inner binding thread.

In Fig. 4E, 85 designates a spool upon which the supply of the inner binding 86 is wound. The said spool is supported upon the inner projecting end 87 of the inner thread guide 24:. The said spool is held upon the said inner thread guide by means of a nut 88 having screw threaded connection with the inner rear end of the projecting portion 87. The inner binding thread 86 extends from the spool 85 through an opening 90 in a guide arm 91 which is intaieeea tegral with or otherwise connected to the nut 88. 'The said arm extend-s radially. from said nut 88 .andislthcn bentjatnd extended. along the side of and parallel with thespool The said inner binding thread also extends.

through eyes 92 formed upon the said guide arm 91. i i a a a 93 designates a tension springlocatedbetween washers 94, one of which is seated against the adjacent end of the spcol 85 and the other one of which is seated against the adjacent side of the plug: or block17.

The pressure of the spring against the spool holds it with more or less firmness against the washer 96 situated between an endof the spool 85, and the nut 88 whereby the spool is prevented from rotation except as desired. Being supported upon the projecting portion 87 of the. stationary guide-24p the spool 85 is not rotated except as the binding thread 86 is drawn therefrom as: it

is pulled forward and twisted by the twister (not shown) in the nanner already s ated.

Openings 97 (only one of, which is sghoiwn)v are provided in the revoluble memberlO: (as is described in connection with Fig; 1) by means of which thespool or carrier 85 may be removed for the purpose of replacing the same with another spool or for, any other purpose. a a l In both forms of construction the spools are located interiorly ofthe revoluble meme ber 10 and are supported; thereon and, the spools are of asize and diameter to permit the ornamental thread guiding: memberv 4i or the ornamental threads 55 to be revolved entirely around, the same,
